The client is always right

I don't know much about other businesses, but in software the client is always right when he is complaining about something. He may not be right about the solution, but if he complains usually there is a problem that needs to be acknowledged. It is the developer's task to find the right solution with the client.
"But the client is not using it the right way!"
It should be more intuitive.
"But I told my client that we should have not implemented that way, and now he is complaining!!!!"
Totally your fault. You could not convince him properly. Try to learn to communicate better.
